rno'roGRAPHIc-FILM CARTRIDGE.

' Specification of Letters Patent.

Patented May 15, 1917.

Original application filed May 18, 1914, Serial No. 639,232. Divided andthis application filed .Tune 30, 1915. Serial No. 37,372.

To all whom it may concern:

Be it known that I, HARRY Ln B. GRAY, of Rochesteigcounty of Monroe, andState of New York, have invented certain new and useful Improvements inlhotographic-Film Cartridges: and I do declare the following to be afull. clear, and exact description of the same, which will enable thoseskilled in the art. to make, use, and practise my inven tion.

This case is a division of niyapplication Serial No." 839,232, filed May18, 191i, for

photographic cameras or holders and films 'therefor, which resulted inPatent, No.

1,192,058, dated July 25, 1 916.

My invention relates to a spool or cartridge embodying a strip ofphotographic film associated with a flexible translucent covering ofsuch permeability to light, that a designation applied on its surfacemay be light recorded through the single thickness of covering materialupon the film, but that a plurality of layers, as isused when thecovering is rolled up with the film, may be substantially opaque toactinic light.

My invention also relates to a film cartridge, adapted to be used with asuitable holder or camera provided with means perniitti-ng autographicdesignations or memoranda to be light printed through the flexiblecovering upon the film, the covering bearing upon its surface one ormore fixed characters such as sequential designations, that may be lightprinted upon the film in proximity to the .mcmoranda.

This cartridge film may be used in any suitable. type of amera involvingany desired method of recording autographic designations, but is'particularly adapted for use in a camera, or holder for sensitized phoThe accompan ymg drawing shows a perspective view of the film cartridgepartially unrolled.

In order that the autographic designations produced in the camera orholder referred to and the numerals or other sequential designations ofthe dill'crent exposures. of the film may be light-printed upon the filmitself and so that the operator may determine the proper feeding of thefilm in the camera, I provide my lihn cartridge of special constructiouadapted to be used in connection with the mechanism described. This'canridge embodies a strip of paper oi sumlar material longer than the filmandcorresponding in-si'zc and shape to the ordinary black paper backingon the film cartridge in general use, but in the present instanceinstead of being opaque and when the cartridge is used for lightrintingdesignations on the film, said paperis more or less translucent andpreferably of an orange red I both ends to the paper in the usual mannerand said paper is provided at its'extreme edge with a designating mark3, adapted to be visible through the usual aperture covered by the usualruby window arranged in the amera back at one edge of the exposingaperture. The paper covering 1 is provided with sequentialdesignatii'ig'marks 4 of such nature that their outlines may be lightprinted upon the film preferably by being printed thereon in black oropaque ink at a distance from the mark 3 equal to the length oftheexposure for which the camera or liolder is adapted, that is to say,substantial y itself. This designation 4 will be visible the length ofthe exposing aperture through the opening in the camera back when the11d or cover is removed, and the flexible covering or carbon paper isslightly narrower than the film, so that When said cover is open, lightentering the camera Will ass through the cover I designation 4 upon thefilm, the ink of said designation preventing the passing of light,

paper 1 and print the so that the number of the exposure will appearinthe negative,- in the camera or holder shown in the patent, as atransparent figure surrounded by a blackened mortise or field.

In using the holder or camera in connection with the cartrid edescribed. the o)-' erator winds the film forward until one of thedesignating marks 3 appears opposite the aperture covered by the window.He then makes the exposure in the usual way, then moves the lock fromthe cover, clamping the film and the covering upon the frame. and with'a pencil or stylus Writes upon the coveringany data relating to theexposure. thus rendering it light permeable on the designated lines andallows light either from the sun or an artificial source to enter theslot and atl'ei-t the film beneath,

not onl through the lines traced by the stylus in the covering but alsothrough the sequential designation 4 marked on the covering paper at theside of the covering. He then closes the cover and for the next exposurewinds forward the film and covering 1 in the usual manner until anothermark 3 appears at the opening covered by the ruby-glass or window.

Inasmuch as the sequential designations printed on the film, In tlusembodiment of my invention are practically in line with the part of thefilm used in making'thc pictures, it is essential that t'he door orcover through which the light printing is accomplished be closed duringthe feeding of the film. i

While it is true that the portion of the film which passes beneath thewindow or,

aperture through which the designation 3 is observed may be foggedorexposed as the film is drawn forward in the camera or holder,this'exposed portion is beside the margin of the exposure aperture andwill, therefore, not appearin the finished negative but is a part of thefilm which is ordinarily wasted.

" -I claim as my invention:

1. A film cartridge consisting of a strip of flexible film and aflexible backing or covering strip of translucent flexible materialassociated therewith having sequential designations printed thereonadapted to be light printed on the film by exposure to actinic light.

2. A film cartridge consisting of a stripof flexible film and a flexiblebacking or covering strip of translucent flexible material associatedtherewith having sequential to be printed on the film by exposure of thefilm to actiniclight passing through the covering and additionaldesignations printed on the margin of the covering at points removedfrom the first mentioned designations.

4. A film cartridge consisting of a strip of flexiblephotographic filmand a flexible translucent covering strip of greater length than thefilm and having a marginal portion cxtendmg'bcyond a side edge of thefilm, said strip having designating marks inside :of the marginalportion adapted to be printed on the film by exposure to actinic lightand further marks on said marginal portion as an aid in positioning thefilm within a camera.

5. A film cartridge consisting of a strip I of flexible film and aflexible covering strip associated therewith having. sequentialdesignations permanently indicated thereon which are adapted to belight' printed on the film by light passing through the strip when thedesignation bearing portion of the covering strip and the associatedportion of the, film are exposed to actinic light.
